This invention has particular reference to devices for tensioning or constricting a binding means whether the same be wire or strap metal, and the subsequent fastening of the constricting material to form a permanent binding. Such a device finds great usefulness in preparing bundles, bales or other packages for shipping or in the assembly of manufactured articles wherever it is desired to lo form a quick and permanent tie. Examples of such use are found in the metal strapping for shipment of bales, cartons, boxes, and

miscellaneous articles and also in the assem- F bly of broom heads or mop heads to handles.

In the application of my invention it is immaterial what the particular form of tying element may be, as the tool is adapted to be used with difierent varieties and forms of tying material. For purposes of illustration I have shown the tool as adapted to placing a binding upon a shipping crate, although the application to other uses will be clearly understood by those skilled in these arts.

terial in order to form a fastening of a permanent nature. By. means of the device described hereinafter it is possible to make such a fastening in a variety of ways dependent upon the demands of the occasion and the nature of the materials upon which the work 1s being done. The device lends itself to the formation of fastenings with or without the utilization of links or keepers When the latter areused the fastening can be made in several different ways, for example by applying the tensioning uponone end of the binding material and clamping it securely in final form. Again it is possible by the use of this device to use nails. or staples for the rapid and secure fastening of the ends as formed. Irrespective of the manner inwhich the device may be used, it consists essentially of the following parts. The member 12 takes the-form of a truncated cone 13terminating in a mouthpiece having two lips 14, 1 1, the outer surfaces of which are tapered as shown igs. 2 and 3. This body member 12 is hollow and has a longitudinal opening 15 between the lips 14;, 14. This opening need not be of greater width than the width of thematerial which is to pass through it, but it must be broad enough to permit two thicknesses of the material to pass as indicated inrFig. 3. The, opposite end of the member 12 carries transverse bearings 16, 1'? formed by notches. Substantially in the plane of these hearings there is attached to the member 12 a handle 18 by riveting, screwthreading or the like. While not essential to the mode of operation, it. is sometimes very desirable, as will appear later in the specification, to have the member 12 slotted throughout its length along one side as indicated at 19. The bearings 16 and 17 receive a shaft 20. This shaft has means such as the hand wheel 21 for rotating the shaft in the bearings. A ratchet 22 is carried on the shaft 20 closely adjacent to'the outer wall of the member 12. Upon the member 12 is pivoted a pawl 23 which serves to engage the ratchet 22 and prevent rotation ofjthe latter while the device is being used to fasten the tie. I

' From Fig.1 it will be noted that the shaft 20 is diametrically slotted along the longitudinal axis of the member 12 as indicated at 24.

Where the member 12 is slotted throughout its length as indicated at 19, the corre sponding slot 24 is carried through the free end of shaft and made to register with slot 19.

The device so constructed may be used in numerous ways, its primary object being to receive one or both ends of the binding wire or strap in the slot- Q l of the winding shaft, and to draw up upon the material until proper tension has been exerted. The material may then be nailed, stapled or otherwise fastened to the object which it is desired to hold or in the event that a link or keeper has been threaded upon one or both ends of the material, the tool may be pivoted on its mouth piece 14 to bend tie material sharply and thus prevent its loosening during a subsequent fastening step. Several modes of use have been illustrated by way of example and in particular Figs. :4, 3., l and 5 illustrate the manner by which both free ends of the binding material may be threaded through the channel 15, slot 19 and slot 24 in which latter the ends are tightly held by a half-turn of the shaft 20. Further rotation of the hand Wheel constricts the binding material and applies the desired tension upon its ends. The provision of sloping lips 14. 14 is important in permitting the pivotal movement of the tool at this point in order to clear the way for attaching each part of the binding material by means of a nail 26 and 27 in succession. 7

During the tensioning operation the pawl 23 prevents reverse movement of the shaft 20, but as soon as the fastening means 26, 27 are applied the pawl is released and the excess ends withdrawn from the tool. They can then be snipped to an appropriate length to permit their being placed in overlapping relation and nailed, as shown at 28 in Fig. 5.

It frequently happens that it is undesirable or impracticable to nail the strap in the above manner and in this case use is made of a link or keeper which may take the form of the flat plate 29 illustrated in Fig. This plate may be given any desired form. it being essential. merely that it shall have a central opening. As indicated in 6, both free ends of the binding strap 25 are passed through the opening in the keeper 29 and then held in the tool in the manner above described. It will in many be found that bending the tool in each direction successively after applying tension will put such a crin'ip in the material as to prevent its inadvertent slipping while the free ends are being withdrawn from the shaft and member 12. The ends are then turned down back upon the keeper in the manner shown in Fig. Thisforms a reasonably secure fastening without additional precautions.

lVhen, however it is desirable to make an even more secure fastening, the keeper may take the form 30 shown in Fig. 10. This may be briefly described as a thin metal plate having a central opening and notched at the four corners to produce upstanding l 31 spaced sufficiently to permit the passage of the strap 25 between the opposing members of the pairs of lugs 31. In Fig. 9 the mode of operation illustrated whereby one end of the strap 25 is brought up through the central opening of keeper 30 and bent down between opposing lugs 31. These lugs are then hammered down over the free end of strap 25. The opposite end of strap which has passed around the article to be secured is threaded through the central opening of the keeper and then throu the winding shaft as already described. an ger tension has been applic I o. l is pivoted or inclined so that its arms lies n the line defined by the 9 to prevent the accithe tool is removed.

It is to be noted that the use of the keepers 29 and 30 are of distinct advantage when combined with the device as above described, in that they serve under conditions to form a fulcrum around which the ends of the material are bent in order to prevent accidental slipping. Again by the use of such a link it is possible to anchor one end of the material to exert the -gull tension of the de vice upon the other free end a- ;l then to bend the material so that it cannot slip loose bcfore its final fastening.

A fastening made with a keeper in this manner is a novel and effective way to apply either strap or wire b'ading. Such minor changes in details of construction as may appear to one skilled in the art are of course comprised within the scope of the invention as defined in the followi claim.
